[0033] A vacuum pump 29 electrically connected to the output end of the controller 20 is fixedly installed on the side of the support platform 4; the exhaust end of the vacuum pump 29 is connected to the inside of the support platform 4; a ball head 30 is fixed to the end of the connecting rod 14; the connecting part 17 includes an L-shaped plate 31 fixedly installed on the telescopic end of the electric push rod 16; a cross plate 32 is fixed to the end of the L-shaped plate 31; a number of hemispherical grooves 33 that are compatible with the ball head 30 are evenly opened on the side of the cross plate 32.

[0034] A piston rod 34 is fixed to the side of the L-shaped plate 31; a piston plate 35 is fixed to the end of the piston rod 34; a piston cylinder 36 that slides with the piston plate 35 is fixed to the bottom of the support platform 4; an exhaust pipe 55 is provided at the end of the piston cylinder 36, and an exhaust pipe 56 is provided on the peripheral side near its end; a one-way valve is provided on both the exhaust pipe 55 and the exhaust pipe 56; support plates 37 are symmetrically fixed to the top of the base 2; an air box 38 is fixed between the tops of the two support plates 37; an air supply pipe 54 is provided on the side of the air box 38; a hose is connected between the air supply pipe 54 and the exhaust pipe 56.

[0035] Working principle of the second embodiment: The rubber diaphragm 11 is constructed from a single or multiple layers of fabric coated on both sides with rubber. Depending on the intended use, different fabrics and rubbers can be used. Commonly used rubbers include NBR, PU, ​​and NBR / polysulfide rubber blends. Silicone rubber, fluororubber, and epichlorohydrin rubber are also available. This type of rubber diaphragm offers advantages such as heat resistance, media resistance, pressure resistance, flex resistance, elastic recovery, and high sensitivity.

[0036] By arranging a one-way valve on the exhaust pipe 55, external air can only enter the piston cylinder 36 through the exhaust pipe 55, and by arranging a one-way valve on the exhaust pipe 54, the air in the piston cylinder 36 can only enter the air box 38 through the exhaust pipe 54, the hose and the air supply pipe 54 in sequence; each group of ball heads 30 rotates freely in the corresponding hemispherical groove 3, and the electric push rod 16 is controlled to start and contract, driving the connecting part 17 to move in the direction close to the support platform 4, thereby squeezing each group of piston parts 12, causing the piston block 13 to slide inward along the inside of the rotating tube 8, and sending the air inside the rotating tube 8 into the hollow cavity through the air pipe 9, so that each group of rubber diaphragms 11 is expanded and raised above the slide groove 5; in this process, the piston plate 35 slides along the inner wall of the piston cylinder 36, sending the air in the piston cylinder 36 into the air box 38 through the hose, and blowing the light guide plate 22 in the corresponding collecting cavity out through the air outlet box 41 onto the corresponding rubber diaphragm 11 that slides into the inflation.

[0037] The servo motor 27 is controlled to start to drive the corresponding guide sprocket 25 to rotate, and the meshing transmission of the driven sprocket 24 and the chain 28 is used to realize the synchronous rotation of each group of rotating parts 7 and the piston part 12, so that the light guide plate 22 slides along the inner wall of the U-shaped guide plate 21 to one end of the support table 4 and is placed directly below the external printing device. The servo motor 27 is controlled to be closed. At the same time, the electric push rod 16 is controlled to start to extend it, and the air in the hollow cavity is drawn back into the rotating tube 8. Each group of rubber diaphragms 11 shrinks and resets to be lower than the slide groove 5. The corresponding light guide plate 22 is placed horizontally on the top of the support table 4. The vacuum pump 29 is controlled to start to remove the air inside the support table 4, so that a negative pressure environment is formed inside it. The corresponding light guide plate 22 is adsorbed through the adsorption hole 6, and then the printing operation is performed, which improves the stability of the light guide plate 22 during the printing process.

[0038] For example three, please refer to Figure 1-11 , this embodiment three makes the following improvements on the basis of embodiment two. Specifically, sliding rods 39 are symmetrically fixed to the top of the base 2; a collection box 40 with an opening on one side is slidably set between the two sliding rods 39; an air outlet box 41 that slides with the side of the collection box 40 is connected to the side of the air box 38; a number of partitions 42 are evenly fixed between the inner walls of the collection box 40 from top to bottom; a collection cavity for storing the light guide plate 22 is formed between two adjacent partitions 42; a number of air outlet slots 43 that are connected to the corresponding collection cavities are evenly opened on one side of the collection box 40; sleeves 44 that slide with the sliding rod 39 are symmetrically fixed on the side of the collection box 40 on both sides of the air outlet slots 43.

[0039] A handle 45 is fixed to the top of the collecting box 40; a mounting plate 46 is symmetrically fixed to the surface of the base 2; a rotating shaft 47 is rotatably arranged between the two mounting plates 46; a driving motor 48 is fixed to the side of one mounting plate 46; the output end of the driving motor 48 is fixedly connected to one end of the rotating shaft 47; a clamping rail is fixed to the side surface of the rotating shaft 47; a lifting part 49 is clamped on the rotating shaft 47; the lifting part 49 includes a rotating plate 50; a rotating hole 51 is provided on the side of the rotating plate 50; a clamping groove 52 which is clamped to the rail is provided on the inner wall of the rotating hole 51; the outer side surface of the rotating plate 50 is provided with arc guide plates 53 coaxial with it from the inside to the outside; the thickness between the inner side surface and the outer side surface of each arc guide plate 53 is consistent with the distance between the two adjacent partitions 42.

[0040] Working principle of the third embodiment: The thickness between the inner and outer sides of each arc guide plate 53 is consistent with the distance between the two adjacent partitions 42. Chamfering is performed between one end of each group of arc guide plates 53 and the outer side of the adjacent arc guide plates 53. The controller 20 controls the drive motor 48 to drive the lifting part 49 to rotate a certain angle. Each rotation process is a group of arc guide plates 53 rotated to another group of adjacent outer arc guide plates 53. Each lifting action drives the collection box 40 to rise to the same height. After each collection box 40 is lifted, the adjacent collection chambers are replaced one by one. After each lifting action, the air outlet box 41 is aligned with the corresponding air outlet slot 43.

[0041] After completing the printing operation of the light guide plate 22, the vacuum pump 29 is controlled to stop and the adsorption of the light guide plate 22 is released. The electric push rod 16 is controlled to start and shrink, so that each group of elastic diaphragms 11 is inflated and expanded to lift up the processed light guide plate 22. The servo motor 27 is controlled to start and rotate in the opposite direction. The rotation of each group of rotating parts 7 transports the processed light guide plate 22 into the corresponding collection chamber, completing the automatic collection of the processed light guide plate 22; the drive motor 48 is controlled to start and drive the lifting part 49 to rotate, so that the adjacent arc guide plate 53 rotates to the bottom surface of the collection box 40, realizing the automatic rise of the collection box 40, and then the electric push rod 16 is controlled to extend and reset, so that each group of rubber diaphragms 11 shrinks and resets. During this process, the piston plate 35 slides outward along the inside of the piston cylinder 36, and the external air is drawn into the piston cylinder 36 through the exhaust pipe 55.

[0042] Repeating the above operation can realize automatic feeding and automatic recycling of the light guide plate 22, thereby improving the efficiency of the dot processing, avoiding contamination of the light guide plate caused by manual handling, and improving the quality rate of the product.

The sleeve (44) on the collection box (40) equipped with the light guide plate (22) is inserted into the corresponding slide rod (39), and the collection box (40) is placed at the end of the innermost arc-shaped guide plate (53). At this time, the bottom surface of the collection cavity at the bottom of the collection box (40) is higher than the top of the support platform (4) and is coplanar with the highest point of the inflated rubber diaphragm (11); T2, control the start of the electric push rod (16) to shrink it, drive the connection part (17) to move in the direction close to the support platform (4), thereby squeezing each group of piston parts (12), making them slide inward along the inside of the rotating tube (8), and sending the air inside the rotating tube (8) into the hollow cavity through the air pipe (9), so that each group of rubber diaphragms (11) are expanded and raised above the slide groove (5); during this process, the piston plate (35) slides along the inner wall of the piston cylinder (36), sends the air in the piston cylinder (36) into the air box (38) through the hose, and blows the light guide plate (22) in the corresponding collecting cavity through the air outlet box (41) to slide into the corresponding rubber diaphragm (11) that is expanded by the inflation; T3, control the start of the servo motor (27) to drive the corresponding guide sprocket (25) to rotate, and realize the synchronous rotation of each group of rotating parts (7) and the piston part (12) through the meshing transmission of the driven sprocket (24) and the chain (28), so that the light guide plate (22) slides along the inner wall of the U-shaped guide plate (21) to one end of the support platform (4) and is placed directly below the external printing device. The servo motor (27) is controlled to be turned off. At the same time, the electric push rod (16) is controlled to be started to extend, and the air in the hollow cavity is sucked back into the rotating tube (8). Each group of rubber diaphragms (11) shrinks and resets to be lower than the slide groove (5). The corresponding light guide plate (22) is placed horizontally on the top of the support platform (4). The vacuum pump (29) is controlled to start to suck away the air inside the support platform (4), so that a negative pressure environment is formed inside the support platform, and the corresponding light guide plate (22) is adsorbed through the adsorption hole (6), and then the printing operation is performed; T4. After the printing operation of the light guide plate (22) is completed, the vacuum pump (29) is controlled to stop, the adsorption of the light guide plate (22) is released, the electric push rod (16) is controlled to start to shrink, so that each group of elastic diaphragms (11) are inflated and expanded, and the processed light guide plate (22) is lifted up, and the servo motor (27) is controlled to start to rotate in the opposite direction. The rotation of each group of rotating parts (7) transports the processed light guide plate (22) into the corresponding collection chamber, and the automatic collection of the processed light guide plate (22) is completed; the driving motor (48) is controlled to start to drive the lifting part (49) to rotate, so that the adjacent arc-shaped guide plates (53) rotate to the bottom surface of the collection box (40), and the collection box (40) is automatically lifted up. The above operation is repeated to realize automatic feeding and automatic recovery of the light guide plate (22).
